标准耐火砖
耐火砖，又称火砖，是由耐热陶瓷材料制作的砖，形状跟普通建筑用砖类似，因此常用于建筑窑炉和各种热工设备。耐火砖一方面在高温下不会有化学变化，一般也是热传导较差的材料。通常致密的耐火砖会用在一些有机械应力、化学应力及热应力的条件下，例如燃烧木材的窑或炉，容易因木材而磨损，沾附灰分或炉渣，而且又是高温的条件。若是其他较不严苛的条件下，例如电窑或天然气窑，使用更多孔隙的“窑砖”会是较好的选择[1]。窑砖较脆弱，但也比较轻，较容易成形，而且隔热效果比厚砖要好。不论是什么情形下，窑砖或耐火砖都不能在快速温度变化时有剥落的情形，其强度也需保持一定程度。

Galvanized Steel Coil HS Code Galvanized Steel Coil
The galvanized coil is a thin steel plate in which a thin steel plate is immersed in a molten zinc bath to adhere a layer of zinc to the surface.Galvanized steel is a surface treatment technique that coats a layer of zinc on the surface of a metal, alloy or other material for aesthetics, rust prevention, and the like. The main method used is hot-dip galvanizing. Zinc is easily soluble in acid and soluble in alkali, so it is called an amphoteric metal. Zinc hardly changes in dry air. In moist air, a dense zinc carbonate film is formed on the zinc surface. In the atmosphere containing sulfur dioxide, hydrogen sulfide and marine, the corrosion resistance of zinc is poor, especially in the atmosphere containing high temperature and high humidity containing organic acid, the zinc coating is easily corroded.
